Preheat your oven to 325°F (165°C) and lightly grease a 4-inch ramekin or small springform pan.
In a medium mixing bowl, whisk together the Greek yogurt, protein powder, egg white, vanilla extract, and almond flour until the batter is completely smooth and lump-free.
Pour the cheesecake mixture into the prepared dish and smooth the top with a spatula.
Bake for 25 to 30 minutes, or until the edges are firm and slightly golden, but the center still has a very slight jiggle.
Remove from the oven and let it cool at room temperature for 30 minutes, then transfer to the refrigerator for at least 2 hours to set.
While the cheesecake chills, place the mixed berries and honey in a small saucepan over low heat.
Simmer the berries for 5-8 minutes, stirring occasionally, until they break down and create a thick, jammy sauce.
Once the cheesecake is fully chilled and set, spoon the berry compote over the top and serve.
